Definitions

  • This invention relates to obstacles used by skateboarders, bikers and in-line skaters to enhance their individual ability and enjoyment. It relates more particularly to an obstacle referred to as a quarter pipe.
  • a quarter pipe is an obstruction which has a shape corresponding to one quadrant of a cylinder with an entry edge of the cylinder being located next to the ground.
  • the quarter pipe thus constitutes a ramp which redirects a rider entering the ramp upward approximately 90° to a platform, cornice or rail which allows the rider to reverse direction and roll down the quarter pipe to ground level.
  • quarter pipes are relatively massive unitary obstacles made of reinforced concrete or the like and because of their cost, they are usually only found in parks and other public spaces. They are not designed for home use.
  • Another object of the invention is to provide such a quarter pipe which is easy to assemble and, when assembled, is rugged enough to withstand prolonged use by skateboarders, bikers and in-line skaters.
  • a further object of the invention is to provide a quarter pipe which, although portable, is quite stable in use.
  • the aforesaid base and entry sections are designed to be filled with a relatively heavy fluid medium such as water or sand in order to increase the weight of the apparatus and lower its center of gravity. This helps to stabilize the quarter pipe and prevent it from moving around when in use.
  • our quarter pipe shown generally at 8, comprises a generally rectangular base 10 in the form of a water tank having a rear wall 10a and a front wall 10b.
  • the base is supported at its comers by a pair of tubular rear legs 12 and a pair of tubular front legs 14.
  • Those legs extend up to a generally rectangular raised deck or platform 16 which is spaced appreciably above base 10 and has a rear wall 16a, a front wall 16b and opposite end walls 16c and 16d.
  • the front legs 14 are more or less vertical, while the rear legs 12 are toed in so that they may be slightly longer than legs 14 in order to maintain deck 16 in a horizontal plane.
  • an inverted, generally U-shaped tubular handrail 18 extends up from deck 16 adjacent the rear wall 16a thereof.
  • the legs of the handrail 18 are aligned with rear legs 12.
  • the handrail is composed of two mirror-image L-shaped sections 18a, 18a connected at their upper ends by a short tube 19 telescoped into the opposing ends of the two sections. The sections may be clamped together around the tube 19 by a clip 20 of the type described in application Serial No 09/991,811, now Patent 6,547,221, the contents of which are hereby incorporated by reference herein.
  • the components of the quarter pipe are dimensioned and spaced so that when assembled, the apparatus is quite stable while in use.
  • the base 10 and entry section 22b are preferably weighted to increase the overall mass of the apparatus and to lower its center of gravity. This assures that when a rider rolls up ramp 22 to deck 16, the weight and momentum of the rider will not cause the apparatus to tip over, tilt or shift relative to the ground.
  • the illustrated base 10 is generally rectangular and molded of a suitable strong, weather-resistant plastic such as polyethylene. Typically its dimensions are 4 ft. by 2 ft. by 4 in.
  • the base is solid or rigidified at the comers so that through holes 32 may be provided to accommodate the legs 12 and 14.
  • the remainder of the base 10 is preferably hollow to provide a fluid tight cavity 34 which may be filled with a fluid such as water or sand in order to increase the weight of the base.
  • one or more holes 36 may be provided in the top wall 10a of base 10 adjacent to the center line thereof to fill up, and drain the fluid from, cavity 34. When the base is filled with fluid, these holes may be closed by suitable plugs 38.
  • legs 12 and 14 When assembling legs 12 and 14 to base 10, the lower ends of the legs are inserted through the comer holes 32 in the base and end caps 40 are secured to the lower ends of the legs so that the comers of the base are supported by the end caps when the end caps rest on the ground or other support surface. Alternatively, the base 10 itself may rest on the ground.
  • deck 16 is also a generally rectangular molded plastic article having dimensions slightly smaller than those of base 10. Typically, the deck 16 is spaced about 3 feet above the ground. However unlike base 10, deck 16 is not hollow. Rather it has an open bottom and a multiplicity of intersecting ribs 42 extend down from the top wall of the deck between the side and end walls thereof to form a grid structure which makes the deck quite resistant to bending and racking forces.
  • the front edge 16b of deck 16 is formed with a pair of aligned notches 52 spaced apart along that edge and separated by a relatively long shelf 54 which projects out from deck wall 16b.
  • the shelf 54 has an upper surface 54a which is generally semi-cylindrical with the same curvature as that of coping rail 24.
  • a pair of side shelves 56 project out from deck wall 16b adjacent to the outboard ends of the notches 52. Shelves 56 are set in from the opposite ends of wall 16b enough to provide clearance of the upper ends of the front legs 14.
  • shelves 56 have semi-cylindrical upper surfaces 56a which are co-linear with surface 54a.
  • the coping rail 24 is provided with a pair of downwardly extending tubular stubs 24a which are sized and spaced apart to telescope into the upper ends of legs 14 when the coping rail is seated on shelves 54 and 56.
  • the legs 14 may be releasably secured to the coping rail 24 by spring-loaded push buttons 58 projecting from rail stubs 24a and which are adapted to snap into holes 59 in legs 14.
  • the washers 60 which sit on the upper end of legs 14 support the front comers of deck 16 in the same manner of the washers 49 over rear legs 12.
  • the coping rail 24 is permanently attached to shelves 54, 56 by suitable threaded fasteners 62 (FIG. 3) inserted from below the shelves and threaded into the rail. This leaves openings 64 between the rail and the rear walls of notches 52 as shown in FIGS. 4 and 4A.
  • the open ends of rail 24 are closed by suitable end plugs 70.
  • each ramp section 22a has a curved top wall 72a and a pair of opposite side walls 72b and 72c which extend down from wall 72a.
  • a multiplicity of ribs 74 extend down from the underside of wall 72a and form a rectangular grid between the side walls 72b and 72c.
  • each section is a molded article of the same material as base 10 and is about 4 ft. long and 2 ft. wide.
  • a series of wedge-shaped keys 76 project out from the side wall 72b of each ramp section 22a. These keys are adapted to key into a corresponding series of wedge-shaped keyholes 78 in each ramp section wall 72c to prevent movement of the two sections away from one another, i.e. in a horizontal manner.
  • a curved tongue 82 projects from the upper end of each ramp section 22a.
  • the tongue 82 is set in from the opposite sides of the ramp section and its length is slightly less than the length of the notches 52 in deck 16.
  • the upper surface 82a of tongue 82 has essentially the same curvature as the shelf surfaces 54a, 56a.
  • each ramp section 22a in order to secure the lower end of each ramp section 22a to entry section 22b, the top wall 72a of each ramp section is formed with a relatively large counter sunk hole 86 having diametrically opposite, laterally extending notches 86a in the edge of the hole. As will be described shortly, the hole 86 is adapted to receive a locking cap 88 which locks the lower end of each ramp section 22a to the entry section 22b.
  • An elongated key or lug 102 projects laterally from side wall 92b adjacent to the bottom of the entry section.
  • a key hole 104 is provided in the opposite side wall 92c of entry section 22b which key hole is arranged and adapted to receive the key 102 of an adjacent quarter pipe 8 so that two or more of the FIG. 1 quarter pipes 8 can be placed side by side and locked together.
  • the key holes 50, 78 and 104 of the quarter pipe 8 depicted in FIG. 1 are adapted to receive the keys 48, 76 and 102 of the similar quarter pipe shown in phantom in FIG. 1.
  • a series of quarter pipes may be locked together to form a wider version of the quarter pipe shown in solid lines in FIG. 1.
  • the upper rear edge segment of entry section 22b is formed with a pair of laterally spaced apart shelves 110 recessed or stepped down from the upper end of top wall 92a, the shelves being separated by a vertical notch 112.
  • Each shelf 110 has an inclined top wall with a discoid promontory 114 centered in the shelf.
  • each promontory is formed with a relatively large locking hole 116 centered in the promontory and which opens into cavity 94.
  • a pair of diametrically opposite notches or keyholes 116a are present at the edge of hole 116, the notches being aligned with the short axis of the entry section.
  • the entry section 22b is designed so that when the lower end segments of the ramp sections 22a are seated side by side on shelves 110, the opposing, keyed-together side walls 72b and 72c of the two ramp sections 22a extend down into the notch 112 in entry section 22b and the holes 86 and notches 81a of the two ramp sections are aligned with the holes 116 and notches 116a in the entry section promontories 114. This allows each locking cap 88 to be inserted down through the corresponding aligned holes 86 and 116. As best seen in FIG.
  • entry section 22b i.e. its cavity 94
  • entry section 22b i.e. its cavity 94
  • gaskets or seal rings 120 are provided on locking caps 88 under their heads 88a so that holes 116 are sealed when the locking caps 88 are locked in place as shown in FIGS. 1 and 5.
  • all of the above-described components of the FIG. 1 quarter pipe 8 may be stacked and shipped along with a bag B containing miscellaneous parts such as the end caps 40, fasteners 62, plugs 70, washers 49, 60, etc. in a relatively small volume package or carton P.
  • a customer may purchase the quarter pipe in that knock-down condition and assemble it in a minimum amount of time, attaching the various components of the quarter pipe in the manner described above.
  • the user may fill the base 10 and the entry section 22b with a fluid to lower the unit's center of gravity and increase its mass so that the unit will not tilt or shift relative to the ground when skaters, skateboarders and the like ride up and down the quarter pipe 8.
  • a plurality of the quarter pipes 8 can be connected together side by side in order to increase the overall width of the obstacle so that the children using the obstacle can perform more intricate acrobatic feats.
